Embodiment 1
[0052] A substation remote forwarding data remote verification system, including a substation, a dispatching master station, and an operation and maintenance center master station; the dispatching master station and the operation and maintenance center master station are connected and communicated through a service bus, and the dispatching master station and the operation and maintenance center master station The substations are respectively connected and communicated with the substation through the dispatching data network dispatching data network;
[0053] The dispatching master station includes the master station forwarding table data service module, the master station data identification module and the data checking module;
[0054] The main station of the operation and maintenance center includes a double telecontrol forwarding data checking module and a main substation forwarding data checking module;
[0055] The substation includes remote generators in Zone Ι and remot...
Embodiment 2
[0067] A remote checking method for substation remote forwarding data based on the remote checking system for substation remote forwarding data, comprising:
[0068] S1, respectively assign unique identifiers as keywords to the forwarding table data of the master dispatching station and the substation, so that the keywords of the same data object in the forwarding table of the master dispatching station and the forwarding table of the substation correspond to each other;
[0069] S2, check the forwarding table data between the dispatching master station and the substation, including:
[0070] S21, the master dispatching station sends a verification request containing the keyword of the data object to the substation, the substation responds to the verification request and returns the point number of the data object corresponding to the keyword in the verification request to the master dispatching station, and the master dispatching station judges the data object returned by the ...
Embodiment 3
[0086] The deployment architecture of the substation remote forwarding data remote verification system is as follows: figure 1 As shown, the dispatching master station and the operation and maintenance center are located at the master station side, the dispatching master station and the operation and maintenance center use the service bus for remote communication through the internal LAN, and the dispatching master station and the substation remote machine use high-performance GSP (General Service Protocol) for remote communication enables multi-vendor substations to adopt unified interaction rules to achieve standardized interconnection.
[0087] There are three modes for remote verification of substation telecontrol forwarding data. One is located at the dispatching main station to realize the forwarding data verification of the main and sub-stations; the other two are located at the main station of the operation and maintenance center to realize the forwarding data verificat...
